PAUL BORN, OF NEIV YORK, N. Y.

BOILER FEED- REG U LATO R.

SPECIFICATION forming part of Letters Patent No. 405,456, dated .T une 18, 1889.

Application filed January 81, 1889. Serial No. 298,166. (No model.)

To all whom. it may concern:

Be it known that I, PAUL BORN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Boiler Feed-Regulators, of which the following is a specification.

This invention has for its obj ect to provide novel and efficient mechanism for supplying a steam-boiler with feed-water and regulating such supply; and this object I accomplish by the features and combination of devices hereinafter described and claimed, reference being made to the accompanying drawing', in which the figure is a sectional elevation of a boiler and feed-water regulator embodying my invention.

In the drawing, the letter A indicates a furnace or fire-place for the boiler B, having a float C, whose stem D passes through the stuffing-box E and connects with lever F. The lever F is connected to the rod G of the slide-valve H, whose steam-chest I communicates with the boiler B. From the steam-chest I lead ports M N to the cylinder K, having the piston L, whose rod O connects with the sinks too low, the float C sinks, and the valve H is moved so as to open the port llLwhereupon the steam forces the piston L to the position shown in the drawing, thus opening the valves Q R. Steam thus flows to the pump U and sets said pump into operation, forcing water through the pipe V into the boiler. Then the water has risen to a sufficient height in the boiler, the float C is raised so as to cause the valve H to close the port M and open the port N. The piston L is then forced to the other end of the cylinder K, whereby the valves Q R are closed and the pumping operation is stopped. On the water in the boiler sinking too low the pumping operation again begins, and continues until enough water has again been forced into the boiler.

If desired, the cylinder K instead of being outside of the boiler B can be placed inside said boiler.

What I claim as new, and desire 'to secure by Letters Patent, is-

The combination of a boiler, a feed-water pump, a steam-pipe connecting the steamspace of the boiler with the pump for operating the latter, a feed-water pipe connecting the pump with the water-space of the boiler, a valve in the steam-pipe, a valve in the feedwater pipe, a steam-cylinder having a valvechest connected with the boiler and provided with a movable valve, a fioat in the boiler having a lever-connection with the valve in the steam-chest, a piston in the cylinder, and a swinging-lever connection between'the piston andthe valve of the steam-pipe leading to the pump and the valve of the feed-water pipeto simultaneously open and close such valves, substantially as described..

In testimony whereof I have hereunto set my hand in the. presence of two subscribing witnesses.

PAUL BORN.
